### Planning and Activities

**Day 1 Teaching**

Use the ITP Number grid to highlight multiples, look for the lowest common multiple of 2 and 3, 3 and 4, 3 and 6, 6 and 9. Then find the highest common factor of 32, 16 and 24, then 12, 20 and 32.**Group Activities: T with Y6**

Y5 -- Derive lowest common multiples and highest common factors. Investigate finding lowest common multiples.

Y6 -- Play games to practise finding common multiples and factors.

**Day 2 Teaching**

Use mental strategies to multiply 2-digit numbers by 1-digit numbers. Aim to reach given targets.

**Further Teaching with Y6**

Write the 0.4 times tables. Use this to multiply 2-digit numbers with 1 decimal place by 1-digit numbers. Check the place value of answers is reasonable.**Group Activities: T with Y6**

Use the in-depth problem-solving investigation ‘LCM Squares’ as today’s group activity.

Or, use these activities:

Y5 -- Investigation to practise mentally multiplying 2-digit numbers by 1-digit numbers.

Y6 -- Derive the 0.6, then 2.6 times table. Investigation to practise mentally multiplying numbers with 1 decimal place by 1-digit numbers.
